European Cable Stranding |
![]() |
| Guidelines have been established for measuring conductor sizes within the European Cable industry. In the past, conductors were normally measured by either their cross sectional area, number and diameter of individual strands, or both. The new system for flexible conductors (column 3 & 4 below) centers around the maximum strand diameter and the conductor resistance. In view of this, some cables may have less strands and a smaller diameter than listed below but still conform to BS 6360, VDE 0295, and IEC 228 by meeting conductor resistance requirements. |
